LOGGING-CAR.

Application filed August 13, 1920.

T0 (ZZZ whom it may concern Be it known that we, HAYDN OswALD VIL- LIAMS and YVILLIAM Josnrir MILLER, both subjects of the King of Great Britain, and residents, respectively, of Sperling and Vancouver, both in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Logging- Cars, of which the following is a specification.

Our invention relates to improvements in logging cars and the object of our invention is to devise an improved form of log support bunk which is comparatively simple in construction and easy of operation capable of being readily adapted to the ordinary logging cars in use at the present time. A further object is to devise a releasable means which will efficiently hold the logs in place and which may be released from the opposite side of the car, thus preventing danger to workmen from logs rolling from the car.

We attain these objects by the construction illustrated in the accompanying drawings in which igure 1 is a perspective view of a logging car with which Our invention is embodied.

Fig. 2 is a side view of the log bunk, partly in section.

Fig. 3 is an end view of the bunk, partly in section.

Fig. at is a detail view of the chain fastening means.

Fig. 5 is a perspective view of the movable chock member.

Fig. 6 is a bottom plan view of the elbow extension.

Similar figures of reference indicate similar parts throughout the several views.

1 indicates a flat car of any approved make to the floor of which adjacent its opposite ends are secured transversely bunks of timber 2 and 3, to the upper face of each of which and at one end are secured fixed chocks 4 and 5 the outer ends of which are upturned. as at 6, so as to form a stop. to prevent the outer row of the lower tier of logs from falling outwardly. Secured to the opposite end of each bunk 2 and 3 are parallel guides 7 and 8. as shown in Fig. 3, between which are slidably mounted laterally adjustable chocks 9 and 10 respectively of similar construction to the stationary Specification of Letters Patent.

Serial No. 403,292.

chocks at and 5, the movable chocks, however, being each provided on their lower faces with a plurality of spaced ribs or teeth 11. 12 and 13 indicate shafts extending longitudinally through the respective bunks 2 and 3 each of which shafts is provided with teeth 14. adapted to engage the teeth 11 of their respective chocks 9 and 10 to lock these in any position to which they may be moved, as is more fully hereinafter described, and in order to enable quick and free engagement or disengagement of the shaft teeth and the chock teeth the latter are arranged slightly inclined on the lower face of the chocks, as indicated in Fig. 5.

15 and 16 indicate operating handles secured to the end of shafts 12 and 13 at the ends remote from the movable chocks 9' and 10. 17 and 18 indicate spring pressed latch members mounted adjacent the handles adapted to be pressed in by them as they are moved around to operate the shafts, the latch members then springing out when the handles have been passed to prevent inadvertent return movement of the handles. The opposite end of each shaft is provided with an elbow, indicated by the numeral 19 in Fig. 2, having a downwardly inclined outer face 20, a downwardly turned reduced extension 21 being provided on the inclined face 20 so that the elbow and the extension form in effect a hook on which the end link of the chain may be engaged. The lower end of the extension is provided with a recess 23 in which normally rests the hooked end 24 of an outwardly spring pressed shaft 25 the engagement of the end 24 of which with the recess 23 prevents inadvertent rotation of the shaft, and the side walls of the recess are made inclined so that the inclined surface of the wall riding on the end 24 as the shaft is turned presses inwardly the shaft 25 and allows the toothed shaft to be operated the amount required. From the foregoing, it will be evident that the extension 21 of the elbow 15 and the hook end 24 of the shaft 25 form in effect a shackle for engagement with one of the chains referred to hereafter.

26 and 27 indicate the chains for binding the logs, each of which chains has a link, indicated by the numeral 22 in Fig. 2, adapted to engage freely the hooked end of its respective shaft 12 and 13 while the opposite end of each chain is secured respectively to I links 28 and 29 secured to the car, these links being wide at their lower ends as at 30 to permit the chains to be passed freely through while their upper ends are reduced,

as at 31, to a width just sufficient to receive a chain link edgewise so that the contiguous link being then on its flat, the chain is securely held from inadvertent displacement.

The manner in which the invention is operated and its utility will be apparent and maybe briefly described as follows :The

logs, indicated'by the numeral 32, are arranged in tiers on the car, the lower tier resting on the guides '7 and 8 and covering plates 33 and 34; under which therespectire checks 9 and 10 slide. These chocks are then adjusted laterally to the width of the tier of 'the extensions 2l, carried over the body of logs, and their free ends doubled and passed through the wide ends of the links 28 and 29, the chains then being pulled tight after which the link of each chain which extends through the respective links 28 and 29 is turned edgewise and placed in the reduced end of the links, being held against disengagement therefrom bythe next chain link which is'turned transversely and thus the lo s are securel bound to the car for transportation. V

On reachmg the delivery point to enable discharge of the logs from the car to be effected the shafts 12 and 13 are operated to carry the shaft teeth 14 clear of the chock teeth .11, this operation at the same time turning the extensions 21 and elbows 19 upwardly so that the chain links 22 free themselves'from the extensions, being assisted by the inclined elbow faces 20, the chocks 9 and 7 10 being forced outwardly by the pressure of the logs so that the discharge of the logs is readily and easily accomplished without danger to the operator. 7

What we claim as our invention is 1. In a logging car, a laterally movable log choclnftoothed on its underside, and a toothed shaft capable of actuation from the opposite side of the car. the teeth of which are adapted to becarried into engagement with the chock teeth to maintain the chock in any laterally adjusted position, said shaft having its end on the movable chock side of the car curved to form a hook adapted to f receive a chain link when the shaft is in the V chock-teeth engagmg position.

2. In a logging car, a laterally movable log chock, toothed on its underside, a toothed shaft capable of actuation from the opposite side of the car the teeth of which are adapted to be carried into engagement with the chock teeth to maintain the chock in any laterally adjusted position, said shaft having its end on the movable chock side of the car curved to form a hook adapted to receive a chain link when theshaft is in the chockteeth engaging posit-ion, said hook having a recess in its point, and a spring-pressed shaft having a curved end the point of which is adapted to seat in saidrecess whereby the said hook and said curved end then form a shackle.
